971.6 33. Specification of Application filed August. 18,

To all whom may concern:

lie it known that l liAJKLllY ll. lillnznnn a eitizen of the l niteil titates. residing at l b s ii the 5 t of Franklin and x o um u 1 loan State o't Ohio, hare inrenteil eertain new aiul usetnl lmpro'cenients 'n insulators. of which the following: is a speeii ieation.

lily invention. relates to the improvement of insulators and especially relates to that type of eleetrieal insulators shown in my "former Patent #8785302 of February fl, 1908, dlltl in which the insulator is formed ot two set-lions of poi-retain or similar-niaterial, sniil seetions being seeureil together by a sei'ew or bolt. whieh is also (l(.rlll;ll{l to seeure the instilator hotly to a part of a building or other supi iori.

The objeets o't my present invention are to provhl a two part insulator of ini'procml eonstruetioinin whieh the duplicate elem-- bers are of simple eonstrurtion aiul atlapteil when properly united to form a substantial integral bmly: to so eonstruet the seet-ions or members oi my improved insulator to avoid the employment of easily broken pro jeetions aml to taeilitate the formation of saiil seetions.

Other objeets of my in .ention will be more fully pointed out hereinafter.

These objeets I aeemnDlish in the manner illustrated in the aeeoinpanying drawing, in which:

Figure 1 is a View in perspeetire oi? my improved insulator hotly showing the seetions thereof titted one to the other. Fig. 2 i: a eentral \ertieal seiaion oi the same. Fig. 3 is a View in perspeetire of one of the, seetions, aml Fig. 4 is a seetional \lDW ot a modified t'orm.

Similar numerals refer to similar parts throughout the sei eral views.

In earr in; out my invention, it employ two separately fox-meal insulator members or sections l of equal size amt corresponding" shape and eonstriurtion. lfiaeh ot' these members comprises a bloek or l))( y, the hltitiS and ends of which are at right angles with aeh other, the. upper'sitle or top of the boil) being formed near one oi. its vertical sides with a transverse substantially ishapeil re-- eess 2, the ilirergingg surtz s oi Whie-h are preferably mirrugateih as shown. On or posite SitlLS oi the reeess 2. the seetion formed with eoinparatirely narrow horizontal n'ieetingz; sinnoes 3 whieh are parallel with the. bottom side of the bloek. From n of:

- t. i, EH 3.

"he inner meeting surtaee 2%. the bloel: is profltlttl with a ilownwarill aiul outwardlv inehnea iaee or diagonal i "iaee sueh as is in- (lieateel at 4. the latter to meet the surf-nee ot' projeetingg' or ho1i2ce-nt:.ir extending shouliler or ledge 5 which eiin'respomis with the upper end portion o'tthe block in which is formed the reeess 2. This shonliler or horizontal extension is likewise termed with a transverse snbstzmtially a'shapecl reeess (t on opposite sides whieh are horizontal meeting surfaces 1".

In oining the members 1 0t my in'iproveil insulator, it will be nnihsrstood that the inclined faces 1i oil aiil nu n'ihers are brought into close eonta with the other and that the i'neeti rtaees 3 and 7 of the upper and lower slniuhlers are likewise made to hear one upon the other. thus prodneing when the parts are so joined a hloelelike body which is pre'ierably oblong in form. although it ohvions that the same may be square or of other 9 1'. ale outline. it will also he rnnlerstooet 1.1a as in my said former patent, the recesses 52 and (i are designed to form when the lJlO l-LS are secured together, wire holding; or clamping ways through which two wires Ina pass and within which said wires nia be securely held. In uniting the members of the insulator hlol: or body, I employ a suitable form of belt or screw not. herein shown, iz 'hieh ies iecl to pass through opposing vertical .5 in the insulator hotly me fliers. these rertieal open-- ending;- downward ings which are llllll l$li9kl at 8 being formed lengthwise oi the block and intersecting the inclined surfaces 5? of said block. P2 will also be UDdQTSiIOUil that the threaehal extension of a screw thus employed, may be utilized to enter an adjacent. frmne member or other insulator support.

It will be ohservetl that. in the construcion of the members of my improved in ilator, have avouleil the employment.- of .e i sual number of projeeting a r interlock parts and have proniueetl sa el in a comparatively simple "form. it will also be understood, that the apprr"iniatei i H'Olitl members of the insulator when uniteil with their inclined faees bearing}; C... against the other, form an inst tor body of great; stiren' th. the nieinbei.. le -em being; ea iiaole.

b It I ot resist n either a re Hea or later. strain.

TEX

an upper outwarilly,

ing figures except that the line of juncture of the parts is not an inclined one but is vertical at 4 and horizontal at 43 and 7 \Vhatl claim, is:

1. A two part insulator comprising correspondingly formed sections adapted to fit one against the other, said sections having 0 )posing wire receiving recesses at diflerent elevations, and inclined abutting faces extending throughout the width of the sections and said sect-ions having opposing "r'astener receiving openings which intersect said inclined faces.

2. A two part insulator body comprising correspondingly formed sections, each sect-ion having one of its faces formed with upper and lower horizontal and parallel shoulder portions, said shoulder portions having wire receiving recesses therein and an inclined face extending throughout the width of the section between said shoulder portions, and means for securing said insulator members in engagement with each other.

In testimony whereof I afiix my signature in presence of two witnesses.
